An o ring also known as a packing or a toric joint is a mechanical gasket in the shape of a torus.
O ring cross section.
It is a loop of elastomer with a round cross section designed to be seated in a groove and compressed during assembly between two or more parts creating a seal at the interface.
As a general definition a microring seal is any o ring that measures less than 1 mm in either inside diameter or cross section.
Apple rubber offers microring seals in more than 2 000 sizes ranging from the largest with an inside diameter or cross section of 039 in.

Manufacturers of encapsulated o rings and industrial gaskets.
O ring cross section the i d.
20 mm inside diameter and cross section the smallest size o ring in the world.
O rings are circular sealing elements with circular cross sections and are mainly used in static applications.
The sizes are specified by the inside diameter and the cross section diameter.
How to measure an o ring.
Until now o ring standards have left a gap between the 1 8 and 3 16 nominal cross sections.
Although the cross section of the o ring is seen as fairly arbitrary there are some distinct advantages to either a larger or smaller cross section o ring.
Ideal for small components such as watches.
Our o rings are manufactured according to metric and imperial international standards such as as 568b din iso 3601 and jis.
In de signing this new group of o rings we left spacing in the part numbers to allow us to add additional sizes should they be required.
Standard metric sizes for o rings are defined by international standard iso 3601 1 2002.
O rings are actually really easy to measure.

Of an o ring gland is primarily influenced by the diameter of the mating surface.

All you need to do is measure the internal diameter id or outside diameter od and the width or cross section c s of the o ring.
